I don't give 5 stars because I don't know how much it does what it claims, I haven't noticed a difference, however I use it occasionally.

Car Vw Polo TDI 1.4 130k km. I was skeptical about this additive, but there was no choice, the check engine light was on due to poor passage of the particulate filter. I used two full tanks of this miracle product and the particulate filter was cleaned! Definitely recommend!

In YARIS 1400, I pushed the engine to 4000 RPM and suddenly the check engine and regeneration lights went off

There has been no change in the number of filter regenerations. I only use good diesel (specifically avio) from the same gas station consistently. If there is sensitivity, it is not saved. OPEL ASTRA J

The product is meant to protect the DPF from particles, it does not clean it. There is another category that is meant to clean the DPF.

The number and duration of dpf regenerations were significantly reduced in two diesel cars. Especially for vehicles that are driven in the city, it is necessary.

Very good, the improvement in the diesel engine of my Audi was immediately noticeable. It greatly reduced the unpleasant smell when it regenerates.

Although I am skeptical about such products, my Yaris diesel now emits less smoke. Maybe it is also due to the colder air. I will come back with an update!

I have used it twice so far as a preventive measure on my BMW F30. After having the DPF checked at my workshop, they told me that the DPF is in very good condition
